Flapping molecule (FLAP) is an emergent class of functional system that shows ultrafast conformational
planarization in the singlet excited state, multifold columnar stacking in a condensed phase, and compulsory
planarization in stretched polymers. Here, representative applications of FLAP are introduced such
as highly sensitive viscosity probe, molecular adhesive with photoinduced melting function, and ratiometric
fluorescent force probe.
